Foxy Behavior: how a Russian fox farm uncovered the basis of canine domestication

by Drew Drabek figures by Nicholas Lue Foxes are not dogs. As a rule, dogs are docile and foxes are feral. You could say it’s in their DNA. But there are exceptions to every rule. A fox raised in captivity might learn to be gentle. A dog who was abused might lash out. Behavior: it’s complicated. There has been great interest in the selective breeding of … Continue reading Foxy Behavior: how a Russian fox farm uncovered the basis of canine domestication

The Race Against Postpartum Depression Takes One Step Closer to the Finish Line

by Melanie Basnak figures by Aparna Nathan Emily gave birth to a healthy baby boy. But, soon after the delivery, she started to feel sad and constantly overwhelmed. She could easily get irritated and was often angry. She worried that something would happen to her baby, and this obsession kept her from sleeping. Even though she had lots of support from her partner and family, she felt … Continue reading The Race Against Postpartum Depression Takes One Step Closer to the Finish Line

Checks and Balances: “Unblocking” the fight against cancer

by Apurva Govande figures by Rebecca Clements The single greatest challenge of fighting cancer is that cancerous cells come from our body’s own cells. Because cancer cells are similar to healthy cells, successfully and specifically targeting cancerous cells with minimal damage to healthy cells and tissue is difficult. A major advance against cancer in the past decade, cancer immunotherapy is a therapeutic treatment that helps our own … Continue reading Checks and Balances: “Unblocking” the fight against cancer

Force for a Cure: How sensing pressure could protect you against malaria

by Tess Whitwam figures by Daniel Utter Imagine for a moment that you’re at a concert, standing close to a large loudspeaker—you can feel the vibrations from the loud music coursing through your body. Then, your friend behind you taps your shoulder, so you turn around, just as someone walks by and steps on your foot, causing you to jump back in pain. All the while, … Continue reading Force for a Cure: How sensing pressure could protect you against malaria

Exploring The Underground Network of Trees – The Nervous System of the Forest

by Valentina Lagomarsino figures by Hannah Zucker When scientists first studied the structure of nerve cells that comprise the human brain, they noted their strong resemblance to trees. In fact, dendrites, the term to describe projections from a nerve cell, comes from the Greek word Dendron, for “tree.” While the connection in the appearance of nerve cells was made to trees, the comparison may have been more … Continue reading Exploring The Underground Network of Trees – The Nervous System of the Forest

When conservation isn’t enough: rewilding lost ecosystems

Last week, a new study reported that the Antarctic’s second largest colony of emperor penguins continues to decline, after warming weather and high winds led to the loss of over 15,000 eggs in 2016. With reports like these becoming depressingly commonplace, environmental biologists are thinking of out-of-the-box solutions to fight the destruction of ecosystems around the world. One popular solution: Rewilding. Rewilding involves active and … Continue reading When conservation isn’t enough: rewilding lost ecosystems

The Computer Science behind DNA Sequencing

by Alex Cabral figures by Sean Wilson In 2003, with the completion of the Human Genome Project, the entire human genome was sequenced for the first time. The sequencing cost nearly $1 billion and took 13 years to complete. Today, the human genome can be sequenced for about $1000 in less than two days. Industry leaders hope to bring that cost down to just $100 within … Continue reading The Computer Science behind DNA Sequencing

Predicting the Next Big Earthquake

by Franklin Wolfe figures by Abagail Burrus Over the past half-century, earthquakes have been the leading cause of death from natural disasters and have imposed dramatic cultural, economic, and political impacts on society. Compounding their inherent physical hazard is how they strike suddenly without obvious warning, and how they possess a ‘fatal attraction‘ for humans—most of the world’s largest cities lie in areas of major … Continue reading Predicting the Next Big Earthquake

Fossil Fuel Companies Invest in Removing Carbon Dioxide Directly from Air

In the Canadian town of Squamish, there’s a small building with a massive fan on its purple roof. The fan is rapidly pulling outside air into the facility. The air enters the outdoors again, but it’s not quite the same. About 75% of the carbon dioxide (CO2) is gone. Run by the company Carbon Engineering (CE), the building is the pilot plant for their technology … Continue reading Fossil Fuel Companies Invest in Removing Carbon Dioxide Directly from Air
